In addition to what the others have said, other ways you can attract readers to hubpages are very simple.
When you write an article, think about people who might be interested in the article and tell them about it.
Tell people that you are a writer, or whatever term you choose to use (author, web content producer) and tell them the web address of your profile.
Print up a few business cards with your profile web address. This can be done inexpensively. All you need are sheets of blank business cards. Each sheet makes about 10 cards. If you have a computer, word processing program and printer, you can print several of them in just a few minutes and give yourself a professional look if you give them to people.
Tell people that if you like the article to please let others know about it.
Also, the more articles you have, the larger your reader audience will be.
